Day 22. Studenterfester.

This past weekend, thousands of young Danes graduated from high school and then promptly proceeded to drink themselves silly. An otherwise quiet and orderly town, Copenhagen turns into a sort of mass pub crawl for 18-year olds celebrating their accomplishment. The students don sailor caps and hire covered flatbed trucks to drive them throughout the city streets while they blast music and lose their voices.

You hear the cacophony approaching for blocks, shattering the Copenhagen calm. Locals honk their car horns like crazy in support of the graduates who are simply keeping up the Danish rite of passage known as studenterfester.

Their joy is contagious. Somehow it's impossible not to smile and wave, all while some hammered blond kids toss their empty beer cans onto the otherwise spotless sidewalks and sing along -- terribly off-key -- to Nicki Minaj.
